Beit known that I, .BENEDICT T. GIBBs, J r., a` citizen of the UnitedStates,.residing at Chicago, in the county of Cook and State of`Illinois,'have.invented a certain new and useful ImprovementinReinforcements for Frogs and Crossings, of which the following is aspecification. 4

Itis often' desirable and necessary to reinforce frogs, crossings andother track structures which are made .of castmetal in Ysucha mannerthat should the casting crack or fracture, the broken parts will besecurely held in placey and kept inl proper alinement. ySuchreinforcement has hitherto been in the form of separatemetaliparts orstraps whichlhave been bolted onto the casting structure; and due to thevibration of the track the bolts and reinforcement loosen and fail torkfunction.

The Yobject of this invention is to so reinforce suchcast metal frogs,crossings or other track structures, in the process of manufacture thatthe reinforcement becomes an integral part of the casting and cannotunder any circumstances become separated therefrom; thereby holding allparts of the casting in proper place should breakage occur and thuspreventing possible derailment of trains passing over the structure. Afurther object of the invention is to reinforce frogs, crossings orother track structures of cast metal with straps or barsk of non-readilybreakable material, so shaped that they are' securely held and ybound inplace by the surrounding cast metal. The invention further consists'inthe means for doing this economically and pro-v viding a device which issatisfactory in use and is not readily liable to get out of Order. Moreparticularly, the invention consists in the features and details ofyconstruction which will be hereaftervmore fully set forthl in thespecication and claims.

Referring to the drawings, in which similar numerals represent the sameparts throughout the several views. y

Figure 1 is a `plan view, partially in section, of a crossing embodyingthis invention in its preferred form.

Fig. 2 is a sectional view on the line 2-2 of Fig. 1. I

Fig. 3 is a side view of that part of the device illustrated in Fig. 2f

l Similarly, Fig. 4 is a plan view of a frog i embodying this inventionin its preferred form.

Fig. 5 is a sectional view on the line 5-5 of Fig. 4:,and s f Fig. 6 isa side view taken at the right of of Fig. 5. V

lAshas'her'etofore been indicated, the in- `,vention applies' generallyto track structures. y For the purposes of illustration, it isshown inthe rst three figures, (1-3) as appliedto la crossingfof cast metal 10and in the remaining figures (l-6) as applied to affrog'11.EXce'pt forthe difference in shapecausedby'the'variations in formi between thecrossing '10 and the frog 11, both of which will be -hereafterreferredto generically as the hard metalmember, the structures are the same andspondingly' lettered. f 1

v cast around pairs of reinforcing strips 12 of non-readily breakablematerial so placed that in the 1inisbed product they lie embedded inopposite sides of the casting and are held rmly in place therein. Onemeans adopted for holding the strips in place consists in inclining ytheupper and lower edges 14 of the bars 12 to the vertical faces of thehard metal member so that the! bars are of greater height on their faceswhich are toward the center of the hard metal member than at the outersides thereof. with the result that the metal o-f the hard metal memberembraces each bar, as clearly appears in the drawings. to preventlateral movement of the jloar with reference to the cast member. Again,the bars are held against longitudinal movement with reference tothehard metal memloer throughvthe use of lugs 15, of the cast metal. lwhichenter `suitably formed y recesses 16 conveniently located along ythe topand bottom surfaces of the bars., Theselugs 15 obviously tend to preventlongitudinal movement of the bars with reference t the hard metalmember, `Either one of these' methods maybe used singly.

The bars are further held in place by providing vcast metal knobs 17-formed integral with the hard metal member itself which How into theholes 18 formed at convenient The holes may bemadetapered orcylindrical, as' desiree. The balk si ttes@ knobs preafl'e SO COITB"vente longitudinal' mover'nentl of' the When made tapered, the taperprevents latr-A eral' movement ofthe bare with reference to the hardmetal member.l f

The result of the complete...construetionv shown and describedl istli'ltthe hard metal members are forall members, which reducebreazkagein and prevent accidents due to breakage of the hard metal member.: y

Having thus described my invention, what Iclaim as new and desire tosecure by Letters Patent, isz- 1. A railroad traokage striictiire of theVto mafintain'ass'embl-y of con'stituentiparts of said memberupon"breakage thereof.ri
